How to get Stir/Shaken certificates
by ryan embgrets 22 Jul '21

22 Jul '21

Greetings. Does someone know where one can get stir/shaken certificates? Are they same as letsencrypt or do I need to obtain them from some other authority. If someone could provide me with a link to that authority it will be very helpful. Thanks again for your help and time. Ryan

Question about MS Teams integration
by Володимир Іванець 22 Jul '21

22 Jul '21

Hello all! Sorry, this is not a direct Kamailio question. I would like to ask for some help from those who already did this. I'm trying to integrate my testKamailio installation with MS Teams. I added the "mydomain.com" to the Domains section (I kept the " mydomain.onmicrosoft.com"). When I tried to create SBC with a " kamailio-dev2.mydomain.com" FQDN I got this error message: We* can't use the "kamailio-dev2.mydomain.com <http://kamailio-dev2.mydomain.com>" domain as it hasn't be set up in the organization. Try again. If you continue to have problems, contact Microsoft customer support.* There were no issues creating a dummy SBC with a " kamailio-dev2.mydomain.onmicrosoft.com" FQDN. Does anyone know how to set up a domain in the organization from MS perspective? Thank you very much! Regards, Volodymyr Ivanets.

serial forking kamailio - twilio
by Filippo Graziola 21 Jul '21

21 Jul '21

Hi all, I have a question for my kamailio configuration which works like this: - INVITE arrives to kamailio - HTTP async request to API endpoint - Resume, use of rtjson module for parallel forking and loop to kamailio itself - One of the invite is "transformed" in serial forking with rtjson module and it is sent with a delay to TWILIO SIP Domain (landline/mobile phone numbers) Twilio is giving me some troubles because it answers with a 200 OK but the call it is still in establishing/ringing on the "landline" side and as expected when reaching the timeout (no answer from phone number on TWILIO side) kamailio is receiving a BYE. Now the question, how to handle next number to call through Twilio? I was thinking of using rtjson_next_route() when handling the in-dialog BYE but as it is not a failure route so it does not work, or I'm doing it wrong. Thanks in advance for any help/hint. Filippo

Re: [SR-Users] Kamailio KeepAlived HA acc_cdrs table record
by Henning Westerholt 20 Jul '21

Hello, I have not tested it, but the dialog database will probably only help in a restart scenario with regarding to dialogs, at least with a standard cfg. Regarding the example below, this would mean starting the primary Kamailio again, then the cdrs should be generated during the hangup from the primary. You can test also to restart the secondary Kamailio, it should then also read the dialogs from the replicated table and generate cdrs at hangup.

But I think this is because the acc module do not register to a callback function for dialog loading on startup for the DMQ replication. This is done for DB loading, but seems to be not implemented yet for DMQ synchronisation. You could open a feature request on our github tracker for this.

Kamailio python_exec getting randomly TypeError
by Voip support 19 Jul '21

19 Jul '21

Dear Kamailio users, I am trying to use a python script using the module app_python3 to do some billing calculations. The only argument i want to pass to the python script is duration which i calculate in event_route[dialog:start] { $dlg_var('call_start') = $TS; event_route[dialog:end] { $var('v_duration') = $TS - $dlg_var('call_start'); So my $var('v_duration') has the duration of the call in seconds. Then i execute from my kamailio.cfg: python_exec("calculateCost","$var('v_duration')"); The script works randomly - sometimes all is good and sometimes it throw error : app_python3 [python_support.c:156]: python_handle_exception(): apy_exec: calculateCost(4): Unhandled exception in the Python code: TypeError: an integer is required (got type NoneType) The above exception was the direct cause of the following exception: Traceback (most recent call last): File "/etc/kamailio/kamailio-python.py", line 282, in calculateCost duration = int(duration) It looks like the kamailio log show calculateCost(4) so argument 4 is passed to python function but once it executes it appear like there is no string/integer but NoneType argument. I cannot figure this out why this randomly happens - maybe it's an app_python3 module issue? Looking to hear back from you! BR, Tom

17 Jul '21

Hello, Does anybody know how i could change white filter in siprelpy in sems? In Kamailio, I got "200 OK" from UE, then add a new header (SBC: mt-reply) and send it to sems server. The sems server remove it: [#7f410fbfb700/4560] [inplaceHeaderFilter, HeaderFilter.cpp:226] DEBUG: erasing header 'sbc' by whitelist I really don't want to remove it. Actually if I knew how i active profile for sip replying in sems, I would be able to solve this. Thanks with regards. -- --Mojtaba Esfandiari.S

rtpengine play_media
by Дмитрий Плаксюк 15 Jul '21

15 Jul '21

Greetings. I'm trying to set up annoncement playback for both parts of the call. I have to play the file after the connection is established. Stop_media (all) must be executed before playing It turns out the construction: .... block_media ("all"); play_media ("all file = / etc / kamailio / sounds / mg1.wav"); Can't find a way to do unblock_media ("all"); after the file has finished playing. There are no sip messages in this process. The call has already been established.
